Bristol Palin hit back at critics she claims are trying to make a mockery of her recent pregnancy news Sunday, declaring that her pregnancy was "planned" and that "everyone knows I wanted more kids."

Last week, the 24-year-old daughter of former governor and Republican vice presidential candidate Sarah Palin, announced that she was expecting her second child nearly one month after calling off her wedding to 2011 U.S. Medal of Honor recipient Dakota Meyer. The single mom acknowledged that the news of her second pregnancy might be "a huge disappointment to my family" but also pointed out that "there's nothing I can't do with God by my side."

On Sunday, the reality TV star shared a sonogram of her unborn baby and emphasized that contrary to media reports, "I do not regret this baby."

"So here are the things you should all get straight before you continue to mock me, judge me, and talk about me," Palin wrote "This pregnancy was actually planned. Everyone knows I wanted more kids, to have a bigger family. Believing I was heading that way, I got ahead of myself. Things didn't go as planned, but life keeps going. Life moves on."

Just hours after Palin's pregnancy announcement on Friday, Meyer spoke out amid ongoing questions about the unborn baby's father. The 26-year-old Marine did not address speculation that he might be the father and instead took to Twitter to talk about the Confederate flag controversy after President Obama condemned it.

"Three ISIS/ISIL attacks and people are talking about banning a flag still," Meyer tweeted to his 65,000 followers.

Palin and Meyer met last year while filming a reality show and got engaged in March. They were scheduled to wed on May 23 in Kentucky but just days prior, on May 18, Palin's mother, Sarah, announced that the wedding was canceled.

Also last week, it was alleged that Palin was once paid $262,500 in 2009 after the birth of her son, Tripp, 6, to become the abstinence ambassador for the teen pregnancy prevention nonprofit Candie's Foundation. She denied these reports via her blog.

"Let's get another thing straight, because I can't tolerate all the talk on this subject. I have never been paid as an 'abstinence spokesperson.' I was employed by the great people at The Candies Foundation," she wrote. "In other words, they are a teen pregnancy prevention nonprofit and I worked for them when I was 18 and 19 — when I could share first hand the challenges of being a teen mother."

Palin sparked controversy during her mother's 2008 White House campaign with former presidential candidate Sen. John McCain, R-Ariz., when it was revealed that she was expecting a baby at 18 with her then boyfriend, Levi Johnston. The news raised questions about their family values.

"When I realized I was pregnant, I knew I would be completely crucified. But I never even thought of aborting this child, NO MATTER WHAT THE CIRCUMSTANCE," she continued. "This is more confirmation on what I've always stood for. I've always been pro-life and I am standing for life now."
